Description

Technical Field

[0001] The utility model relates to the technical field of folding ladders, in particular to a folding ladder for rescue. Background Art

[0002] At present, the existing ladders are generally used on planes, with support from the support, and most importantly, they can stabilize the telescopic legs, so that the ladder can prevent sliding and tipping, and finally reach the goal. However, for some work occasions, the ground is uneven, and the fulcrums of the ladder are not located on the same plane, and some fulcrums become suspended, which will cause safety problems when working on the ladder. When the ladder is in use, it is possible to slip and tilt. In summary, the following problems exist in the prior art: in the case of uneven ground, some fulcrums of the ladder become suspended, and the ladder cannot support the ground. During the use of the ladder, the ladder will slide and tip over, and finally it is unsafe to work on the ladder. Among them, a ladder with application number "CN202010587898.2" has a simple structure and does not need to be adjusted by hand. When the ground is uneven, the telescopic legs of the ladder can automatically fit on the uneven ground. When the telescopic legs of the ladder are in contact with the ground, the locking structure of the ladder can fix the telescopic legs of the ladder to prevent the telescopic legs of the ladder from sliding. When the ladder is in working condition, the stabilizing component of the telescopic legs of the ladder can strengthen the ladder so that the ladder can stand stably on uneven ground. However, the ladder still needs some improvement during use: since the first ladder column and the second ladder column are fixed structures, the ladder is not easy to fold and store, which occupies a large storage space and is not convenient to carry during the rescue process, thereby reducing the usability of the ladder.
